摘要
本文介绍了汞热释谱技术及在找铀矿、金矿中的应用。其主要内容是；成矿期石英的ＨｇＳ／ＨｇＣｌ２比值的Ｒ＞１，而矿前期石英Ｒ＜１；岩石的矛热释话通常为低温（＜２８０℃）普通峰，而矿石、矿物的汞热释谱则为中温（２８０—６００℃）、高温（６００—８００℃）特征峰；在矿床中汞化合物具有水平分带性：ＨｇＳ在内带，ＨｇＣｌ２在外带；成功地应用于对硅化带合矿性评价。
This paper introduces the pyrolytic-Hg spectra technique and its application to prospecting for uranium and gold deposits,main contents of which are as follows:The ratio of HgS/HgCl2 for ore-stage quartz R>1;whereas for pre-ore stage quartz R<1;Pyrolytic-Hg spectra of rocks are usually at low temperature(280℃)with common peak, whereas pyrolytic-Hg spectra of ores and rocks are at middle temperature(280-600℃)and high temperature(600-800℃)with characteristic peak;Mercury compound in the inner zone,HgCl2 in the outer zone;This technique is successively applied in the evaluation of ore-bearing degree of silicification zone.
